A Comprehensive Exploration of the Atomic Bombings of Hiroshima and Nagasaki

The dropping of atomic bombs on Hiroshima and Nagasaki that occurred in August 1945 is an important and disastrous turning point in human history. Besides ending World War II, these bombs gave rise to a new era of nuclear integration, shifted currents of international affairs as well, and subjected humankind to the fear of unprecedented amounts of mass demise. 

This blog explores in depth the historical background, the chronology of events leading to the bombings, the short- and long-term impact of the event, the long-term effects on the human psyche, and how the event continues to linger as a legacy and a debate that continues shaping world discourse to date. The Pacific War still raged in the second half of World War II.

When were the atomic bombings of Hiroshima and Nagasaki?

It was also the terrifying firebombing campaign of the United States Army on the Japanese, as is reflected in the infamous March 1945 bombing of Tokyo alone, when no less than 80,000 Japanese were killed on a single night. Unlike the Allies, which already had an unconditional surrender of Japan by Nazi Germany, this stance was caused by a desire not to lose the emperor and to avoid occupation. 

In such a stalemate, the then US president Harry Truman, having only become acquainted with the success of the Manhattan Project to develop atomic bombs, had to face the horrifying prospect of a costly ground invasion of Japan, dubbed Operation Downfall, which was projected to inflict tens of thousands, perhaps millions, of wounds on the Allies and Japanese. Truman also used the dropping of atomic bombs to prove to the Soviet Union, which declared war on Japan early in August 1945, the strength of the United States and that the war would end promptly and without additional losses of lives among the Allies.

The atomic bomb was one of the best-kept secrets during the time of World War II. It and the personnel who made it were the work of thousands of scientists aided by a project referred to as the Manhattan Project and overseen by J. Robert Oppenheimer, the director of the Trinity Test, which on July 16, 1945, was successful in testing a plutonium weapon in the state of New Mexico. In July, the US had already assembled two bombs, the plutonium-239, called Fat Man, and the uranium-235, called Little Boy. 

The important attacking cities that were selected were Hiroshima, Kokura, Niigata, and Nagasaki; many of these sites were selected because of their military targets and morale importance. The Little Boy bomb dropped out of the Enola Gay, a B-29 airplane, at 8:15 am on 6th August 1945, and fell on Hiroshima. The explosion of the bomb was recorded at an 580 meters and an energy production of about 15 kilotons of TNT. The sound waves of the city moved with the highest speed since the temperatures caused by the fireball were approximated between 4,000°C and 7,000°C.

The aftereffects of the atomic bomb on Hiroshima and Nagasaki

Due to the US atomic bombing of Hiroshima and Nagasaki, there was the destruction of nearly 70 percent of all the buildings were destroyed or severely damaged. About 78,000-80,000 of the 350,000 population of the city died instantly. By the close of the year 1945, it is estimated that 140,000 people died due to radiation sickness and injuries, and about 38,000 of them were children. 90% of the doctors
